hello I have a vector of 10 components - [1 1 1 1 1 1 0 0 0 0] I want to randomly (a uniform distribution is preferred) mixing the components of the vector, while making sure that in the end I will have the same amount of 1 and 0 as in the beginning.
a desired result for example: [1 0 1 0 1 0 1 0 1 1]
